Good read and very informative... especially the effort towards metal slides and barrel compatibility.

There's another reason you'll want to upgrade to a steel or metal mag-catch. Constant reloading of the mags will cause the plastic part to deteriorate and fail. This in turn reduces gas efficiency when the space between the gas output port and the loading nozzle increases and not delivering all the gas to the BB and BBU. The use of a larger/extended mag will only speed up this deterioration in stock plastic parts.


I also wanted to add my experience with the 5ku steel sights and the Silverback slide mounted dot sight on my G17:

- 5ku Steel Night Sights: fit in my Shooter's Design slide with some minor filing (which is quite common when you're trying to fit metal sights on a metal slide), and held the BBU in place perfectly (provided you didn't only file down one side of the rear sight to fit).

- Silverback slide mounted optics: fits with very minor filing to fit (literally a minute or less of filing to get it to fit). It should be noted that the adapter is made to fit real-steel docter sights and docter sight clones. I had to file down the front nubs on top to make it fit my NCStar Dot Sight.



And also my other experience with other parts:
- Real steel Magloc thumbrest: Fits, no modification to the part or gun is necessary. All included hardware was included to make it fit, directly from the manufacturer. Due to TM's design being slightly wider than its real steel counterpart, the thumbrest is stretched a little bit so it doesn't sit flat against the back of the grip. You can add something in between the thumbrest and the grip to keep it completely stable. I added 2 small layers of velcro to get it to sit perfectly without movement.

- This thumbrest will help with gun control during consecutive shots and will help you place your hand on the grip consistently in the same place, which will help muscle memory and accuracy. Only drawback... when you use a 1911, you'll place your thumb on the safety. lol


- Magpul Speedplates: Perfect replacement part for the mag base plates. Ensures faster and positive reloads and helps to protect your mag if it hits the ground. Only issue is gassing up the mag while these are on... nearly impossible. I suggest disabling the baseplate locking feature so it can slide down so the input valve can be easily accessed.

And also a quick question:
Does anyone know if the piston head/cup for the hi-capa/1911 will fit the G17? And same with the floating valve?
